Ingredients
Scale
- 1 pound ground beef: The foundation of your burger, providing rich, juicy flavor.
- 1 teaspoon salt: Essential for seasoning and enhancing the beef’s natural taste.
- 1/2 teaspoon black pepper: Adds a subtle spice to balance the flavors.
- 1 tablespoon Worcestershire sauce: Infuses the patties with deep, umami richness.
- 2 large onions, thinly sliced: The star of the show, providing sweetness and depth.
- 2 tablespoons butter: Used for caramelizing the onions to achieve their rich flavor.
- 1 tablespoon olive oil: Helps to cook the onions evenly without burning.
- 1 teaspoon sugar: Enhances the caramelization process, adding a sweet contrast.
- 1 cup beef broth: Adds moisture and depth to the caramelized onions.
- 4 slices Swiss cheese: Melts perfectly over the patties, adding creamy texture.
- 4 brioche buns, toasted: Provides a soft, slightly sweet base for the burgers.
- Fresh parsley, chopped (for garnish): Adds a fresh, herbaceous note to finish the dish.
Instructions
Caramelize the Onions:
- Heat butter and olive oil: In a large skillet, heat 2 tablespoons butter and 1 tablespoon olive oil over medium heat.
- Cook the onions: Add 2 large sliced onions and cook, stirring occasionally, until they become soft and golden brown, about 15-20 minutes.
- Add sugar: Sprinkle 1 teaspoon sugar over the onions and continue to cook for another 5 minutes until they are deeply caramelized.
- Simmer with beef broth: Pour in 1 cup beef broth and simmer until the liquid is mostly absorbed, about 10 minutes. Set aside.
Prepare the Burger Patties:
- Mix ingredients: In a mixing bowl, combine 1 pound ground beef, 1 teaspoon salt, 1/2 teaspoon black pepper, and 1 tablespoon Worcestershire sauce. Mix until just combined.
- Form patties: Divide the mixture into 4 equal portions and shape them into patties.
Cook the Burger Patties:
- Heat the skillet or grill: Preheat a skillet or grill over medium-high heat.
- Cook the patties: Cook the burger patties for about 4-5 minutes on each side, or until they reach your desired level of doneness.
Assemble the Burgers:
- Melt the cheese: Place a slice of Swiss cheese on each patty and let it melt.
- Toast the buns: Ensure 4 brioche buns are toasted and ready.
- Layer the ingredients: Place the burger patties on the bottom halves of the toasted brioche buns. Top each patty with a generous amount of the caramelized onions. Garnish with chopped fresh parsley.
Serve and Enjoy:
- Complete the burgers: Place the top halves of the buns on the burgers.
